Martin Kleppmann & Ink & Switch

Their manifesto sets out software where your data lives on your own devices, works offline, stays private, and outlives any company — you own it, not a server somewhere.

This is Orbit's architecture, not a marketing line. It reads your messages on your own Mac and sends nothing to a server it doesn't run. The most sensitive data you have — who you talk to and what you say — never becomes someone else's inventory. Privacy isn't a setting here; it's the shape of the thing.
